20″ iMac G4 (Late 2003)

20-inch iMac G4

The biggest iMac to date, the 20″ model has a 1680 x 1050 display – and due to the weight of the screen, the base has to be heavier to counterbalance it. At 40.1 pounds, this is the heaviest iMac G4 yet.

Except for the screen size and weight, the 20″ iMac G4 is identical to the Late 2003 17″ model.
